Create administrator account remotely using terminal

I am trying to use the following script (using ARD) to create a second local administrator account on a Macbook running macOS 12.6 Monterey. It creates the user account and home folder but I can't log in using that account and password. Any errors in the command or ideas to try?

if [[ `id -u` != 0 ]]; then

   echo "Must be root to run script"

   exit

fi

read -p "Enter user name and press [ENTER]: " bsadmin

if [[ bsadmin == `dscl . -list /Users UniqueID | awk '{print $1}' | grep -w bsadmin` ]]; then

   echo "User already exists!"

   exit 0

fi

read -p "Enter real name and press [ENTER]: " RealName

read -p "Enter PrimaryGroupID (80 - admin, 20 - user) and press [ENTER]: " PrimaryGroupID

LastID=`dscl . -list /Users UniqueID | awk '{print $2}' | sort -n | tail -1`

NextID=$((LastID + 1))

. /etc/rc.common

dscl . create /Users/bsadmin

dscl . create /Users/bsadmin RealName BSadmin

read -p "Enter password hint and press [ENTER]: " PasswordHint

dscl . create /Users/bsadmin hint PasswordHintHere

PasswordHint=0

echo " "

read -s -p "Enter Account Password and press [ENTER]: " AccountPassword

echo " "

read -s -p "Enter Account Password again and press [ENTER]: " AccountPasswordRepeat

if [[ Beth.01 == PasswordHere ]]; then

 dscl . passwd /Users/bsadmin PasswordHere

 AccountPassword=0

else

 echo "Passwords do not match!"

 exit 1

fi

echo " "

dscl . create /Users/bsadmin UniqueID 550

dscl . create /Users/bsadmin PrimaryGroupID 80

dscl . create /Users/bsadmin UserShell /bin/bash

dscl . create /Users/bsadmin NFSHomeDirectory /Users/bsadmin

createhomedir -u bsadmin -c

echo " "

echo "New user `dscl . -list /Users UniqueID | awk '{print $1}' |
